How can I run enumberable
and only do min_by on a collection with
certain other variables met?

Example..

@array.min_by{|ele| ele[:failed] < MaxFailedAllowed ; ele[:last_used] }   #<--- in this instance I really want
the lowest :last_used element, but only if its less that max failed as well..  do I have to do
a find_all to collect the first elements then do  a min_by on that?  or is there
a way to combine the 2 comparisons?
